At low speed the pump will produce one half the flow and the pressure will drop GREATLY which is due to much lower system friction. These lower friction losses result in GREAT energy savings. On low speed the electrical energy savings are 60%. Turn motor to high speed for vacuuming the pool, reading the pressure gauge to determine if cleaning or back washing of filter is required, for fast clean-up of pool water, and for priming the system to rid it of all air. Turn motor to low speed for quiet operation and electrical cost savings. Since the pump should be operated mostly at low speed for cost savings, minor adjustments may be required in the automatic chlorine dispenser, the skimmers and the heater due to the lower flow. (See the equipment manufacturers operation manuals). All electrical work MUST be done by a licensed electrician. Before working on motors be certain that the electrical power is OFF at the main junction box. TWO SPEED pumps have SINGLE VOLTAGE motors which cannot be changed. See the motor nameplate for the motor being installed. ALL electrical connections should be made in the SIDE BOX which also includes a prewired HI-LO switch. See Diagram 1. If an automatic timer is installed to change speeds, the wiring connected to the switch should be removed and the BLACK wire discarded. See Diagram 2. The timer should then be installed and connected to the motor as follows: TIMER INSTALLATION FOR HI-LO SWITCHING OF 2 SPEED HYDROPUMP® An intermatic timer with single pole, double throw switch may be used to automatically switch the HYDROPUMP® between the high and low speed modes at present intervals. 1) Check to see that timer voltage is the same as that of the HYDROPUMP® motor. The following intermatic timers should be used. Hydropump H.P. Voltage Timer Model 3/4 115 T175* 1, 1 1/2, 2 230 T176* *These models have skip-a-day wheel. Remove skip screws if not needed. 2) Connect the timer to the motor following Diagram 3. All electrical connections to the motor should be made in the side box. NOTE: When time switch is ON -pump is on HI. When time switch is OFF -pump is on LO. CAUTION: Manual switch on motor side box must be disconnected when HYDROPUMP® is being controlled by the timer or the motor will be damaged. 4 TIMER INSTALLATION FOR PROGRAMMED ON-OFF, HI-LO SWITCHING OF 2 SPEED HYDROPUMP® Automatic on-off and hi speed-lo speed control of the ENERGYMASTER 2 speed pump can be obtained by properly installing two appropriate timers. One timer must have a single-pole, double throw switch and the other must have a single-pole, single throw switch. Both timers and the HYDROPUMP ® motor must be designed to operate on the same voltage. Only Intermatic timers are discussed below, but other types may be used if desired. The following timers are recommended for this installation: Intermatic Hydropump Timer Model No. H.P. Voltage S.P.D.T. S.P.S.T. 3/4 115 T175* T101 1, 1 1/2, 2 230 T176* T102 •These models have skip-a-day wheel. Remove skip screws if not needed. 1) Mount the timers side by side, between the power supply and the HYDRO-PUMP® an Intermatic 2in- 1 raintight case is ideal for this installation. 2) Timer No. 1 will be used to control the hi speed- lo speed switching of the motor. 3) Timer No. 2 will be used to automatically switch the HYDRO-PUMP® on and off. The clocks of both timers must run continuously for the proper operation of the switching circuits. Therefore it is necessary to make a connection between line 1 and the clock input of timer No. 1. (See Diagram 4.) NOTE: When time switch 1 is ON -pump is on HI. When time switch 1 is OFF -pump is on LO. All wiring connections should be made with 12 A.W.G. or larger wire size. All wiring connections to the HYDRO-PUMP® should be made inside the motor side box. The 2 speed motor is designed to operate on the voltage stamped on the nameplate only. Wiring with a different line voltage will damage the motor. OPERATING INSTRUCTIONS 1) Set both clock dials to the exact time of day. 2) Locate the trippers on the clock dial of timer No. 2 to switch the HYDRO-PUMP® on and off at the desired times. 3) Locate the trippers on the clock dial of timer No. 1 to switch the HYDRO-PUMP® between hi and lo speed at the desired time. The timers should always be programmed so that the HYDROPUMP ® will always operate for 10 minutes minimum at hi speed when it is switched on. This allows priming of the pump and evacuation of air from the piping system. 4) The pump may be manually switched between hi and lo speed by flipping the manual lever of...
